SPI, invented some four decades ago, is so successful as a low-pin-count interface for microcontrollers and processor cores that it spurred memory makers to incorporate both the physical signaling interface and advanced memory command protocols into serial flash and serial pseudo-SRAM (PSRAM) devices. Those protocols, … Read More

WEBINAR: Intrinsic Techniques in RF Power Amplifier Design
Load-pull power amplifier (PA) design techniques determine the optimal impedances at the power transistor’s extrinsic reference plane, which is the physically accessible boundary for measurement or simulation. This reference plane can be the package transistor leads, die bond pads, or IC chip terminals. It includes… Read More
Securing UALink in AI clusters with UALinkSec-compliant IP
A classic networking problem is securing connections with encrypted data, but implementing strong encryption algorithms at wire speeds can limit performance. However, introducing blazing-fast connectivity without an encryption strategy leaves systems vulnerable. The architects in the UALink Consortium, including … Read More
WEBINAR: HBM4E Advances Bandwidth Performance for AI Training
The rapid proliferation of LLMs and other AI applications, and of high-end GPU platforms that run them, is putting intense pressure on the performance requirements for memory technologies. Designers need to be keenly aware of how to make the most of their memory and controller choices, which can be moving targets given the rapid… Read More
WEBINAR: Two-Part Series on RF Power Amplifier Design
At lower frequencies with simpler modulation, RF power amplifier (PA) designers could safely concentrate on a few primary metrics – like gain and bandwidth – and rely on relaxed margins to ensure proper operation in a range of conditions. Today’s advanced RF PA design is a different story. mmWave and sub-THz frequencies introduce… Read More
